I participated in the organization of some meetings:
10-11 octubre 2019, Facultad de Ciencias Físicas UCM Madrid
International Meeting of the Spanish Astronomical Society SEA2018
16-20 July 2018 , Salamanca, Spain
2nd Iberian Nuclear Astrophysics Meeting on Compact Stars
22–23 September 2011, Salamanca, Spain
We were focused on compact stars in a variety of ways ranging from computational simulations, observation and theoretical nuclear astrophysical models. We organized an international workshop, the II Iberian Nuclear Astrophysics meeting in September 2011 on these subjects.

XII Multidark Workshop on Dark Matter
15-17 April 2015, Salamanca, Spain
Elucidating the nature of dark matter constitutes a key challenge in modern physics. MultiDark is a Spanish Project supported by the Consolider-Ingenio 2010 Programme of the Ministry of Science and Innovation, in which experimental and theoretical physicists, astrophysicists and cosmologists join efforts to take up this task from a multidisciplinary perspective.
